Hastelloy C-276® alloy (round steel 2.4819 / NiMo16Cr15W / C276) yog nickel-molybdenum-chromium wrought alloy uas feem ntau suav hais tias yog ntau yam corrosion-resistant alloy. Cov hlau no tiv thaiv kev tsim ntawm cov qoob loo-txheej txheem precipitates nyob rau hauv weld tshav kub-cuam tshuam cheeb tsam, yog li ua rau nws haum rau feem ntau cov txheej txheem tshuaj siv nyob rau hauv raws li-welded mob. C-276 alloy muaj qhov ua tau zoo heev rau kev xeb hauv zos thiab rau ob qho tib si oxidizing thiab txo cov xov xwm.
Nws yog siv nyob rau hauv cov roj desulfurization tshuab vim nws zoo heev tsis kam mus sulfur tebchaw thiab chloride ions ntsib nyob rau hauv
feem ntau scrubbers. C-276 alloy muaj kev tiv thaiv zoo heev rau pitting thiab kev ntxhov siab-corrosion tawg.
